It is in its navy that Great Britain’s chief warlike strength exists, the naval force being much greater than that of any other nation. It possesses in all 29 modern battleships, many of them of the great dreadnaught and super-dreadnaught type. In addition it has 10 cruiser battleships, and 38 older battleships, most of the latter likely to be of little service for warlike duty. There are also 45 first-class, and 70 second and third-class cruisers, 58 torpedo boats, 212 destroyers and 85 submarines, the whole forming a total navel strength approaching that of any two of the other Powers. SERVIA AND BELGIUM As regards the remaining nations engaged in the war, Servia, in which the contest began, has an area of 18,782 square miles, a population of 4,000,000, and a standing army of 240,000, a number seemingly very inadequate to face the enormously greater power of Austria-Hungary. But the men had become practically all soldiers, very many of them tried veterans of the recent Balkan War; their country is mountainous and admirably fitted for defensive warfare, and their power of resistance to invasion was quickly shown to be great. Belgium, the other early seat of the war, is still smaller in area, having but 11,366 square miles. But it is very densely populated, possessing 7,432,784 inhabitants. Its army proved brave and capable, its fortifications modern and well adapted to defense, and small as was its field force it held back the far more numerous German invaders until France and Great Britain had their troops in position for available defense. This small intermediate kingdom therefore played a very important part in the outset of the war. If one judges by the figures given of the available military strength of the nations involved, the huge host said to have followed Xerxes to the invasion of Greece could easily be far surpassed in modern warfare. The fact is, however, that these huge figures greatly exceed the numbers that could, except in the most extreme exigency, be available for use in the field, and for real active service we should be obliged to greatly reduce these paper estimates. It must be taken into account that the fields and factories of the nations cannot be too greatly denuded of their trained workers. It was a shrewd saying of Napoleon Bonaparte that “An army marches on its stomach,” and the important duty of keeping the stomach adequately filled can not be overlooked.
